Water tank cleaning in Al Awali Makkah

Al Awali is a modern villa district in the south east of the city, built in the nineteen nineties on the high ground that named it. Planned streets lined with luxury villas each with private plots, gardens and boundary walls surround individual tanks buried below or on rooftops. Water cuts off in summer and the small individual tanks empty fast when garden irrigation runs.

Why the job is different in Al Awali

Each villa has its own separate small tank and a large garden with shrubs and trees that draw water daily. Tanks empty quickly in summer from garden irrigation and household use combined. The method is set out in full on Water tank cleaning in detail.

The first reason

Private gardens draw water continuously every day

Each villa has a garden of significant size, watered by manual and automatic systems. The small tank empties fast from both irrigation and household use together, so water cuts out in summer.

The second reason

Small tanks accumulate sediment very fast

A small tank needs frequent cleaning because the proportion of sediment to water volume is high. Deposits form and compress much faster than in larger shared tanks.

The third reason

Irrigation pipes draw directly from the tank

Irrigation pulls from the tank without filtration, so sand and soil from the garden may enter the tank itself. Mixed use drives up sediment and creates faster blockages.

The character of Al Awali

Villa district: private plots, gardens and a boundary wall to every house

Villas with gardens mean the tank serves both household use and irrigation, so the tank is small for the total demand. Small tanks and large gardens create intense pressure on water supply. Cleaning requires special understanding of mixed-use pipes and garden irrigation filters.

Before treatment

The condition of the tank decides the method

A villa district of luxury homes in the south east with large private gardens and complex irrigation systems in each plot. Tanks are small and numerous, each serving one home.

Fine brown sediment beneath shallow water

The layer on the floor

The floor layer is debris and sand from old irrigation filters and sediment from water standing when the tank is not in use.

Light and algae

Algae grow quickly in small tanks exposed to light and water left still overnight when no irrigation runs.

A damp concrete wall carrying a dark deposit

The deposit on the wall

The wall deposit builds fast from sediment and corrosion, and small tanks are affected much more severely than large ones.

A concrete surface with a fine hairline crack

The lining and hairline cracks

Hairline cracks may start from pressure fluctuation as automatic irrigation opens and closes valves rapidly.

The lid of a water tank on a building roof

The lid and the access hatch

The lid and access hatch are close to the garden and collect leaves and dust from garden activity.

A plastic pipe leaving the exterior wall of a building

The vent and the overflow pipe

The vent can be blocked by garden debris or sand from the irrigation, so it must be cleared of blockages.

How we work

1
Inspect before the drain

Tank type and material, the condition of the lining, the depth of the sediment, the lid and the vent, and where the drained water will go. We agree the window without supply before anything is opened.
2
Drain, then lift the sludge

The water leaves through the outlet, then the layer beneath it is taken out by hand and by suction. That layer is the reason for the visit, not the water that ran out ahead of it.
3
High pressure wash

Walls, floor and the joint where they meet, with a brush wherever the film resists, then the wash water is taken out completely so nothing we lifted settles again.
4
Disinfect and put back in service

Disinfectant over every internal surface, left for its contact time and then rinsed out, followed by the refill, a first draw off at the taps, and a report on what was inside the tank.

What water tank cleaning includes

An inspection before the valve

Tank type, lining condition, depth of sediment, lid and vent, recorded before any water leaves.
Full drain and sediment removal

The water through the outlet, and the layer below it by hand and by suction until the floor itself is showing.
Pressure washing walls and floor

High pressure across the surfaces and corners, and a brush on anything water alone will not lift.
Disinfection after the wash

A disinfectant intended for drinking water tanks, named to you before it is used, left for its contact time and then rinsed out.
Refill and the first draw off

We refill, run the taps so the new water moves through the pipework, and tell you when it is ready to use.
A report and the next date

What was inside the tank, anything on the lid or the lining that needs repair, and a sensible date for the next clean.

Questions about this district

Why does the water cut off in summer? Is the tank too small?

Yes, villa tanks are small and must serve both the house and the garden. Summer use is very high and the tank drains fast.

Should we enlarge the tank or reduce the garden watering?

Enlarging the tank is easier than reducing the garden. Cleaning the existing tank improves distribution efficiency as a first step.

Does the garden water smell rusty from corrosion?

Small tanks corrode faster because water stands longer. Cleaning and disinfection removes rust smell and restores the water.

The irrigation filters deposit sand into the tank. What can we do?

The filters may be clogged or old. We recommend cleaning the filters first. Regular tank cleaning removes the sediment they release.

Should irrigation and drinking water pipes be completely separate?

Yes, they should be in well-planned systems. However, some older villas mix the sources in the same pipes.

How often should we clean the small villa tank each year?

Two to three times yearly, because small tanks need more frequent cleaning. In summer, an extra clean is wise to manage the sediment load from irrigation.

How much does water tank cleaning in Al Awali cost?

It is set after the inspection, because the price follows the type of infestation, the size of the space, how far it has spread and the number of visits it needs. Send a photo and a description on WhatsApp and we will give you an estimate before we reach Al Awali.
